…IVF vector index on embedding column

Problem:
The BigQuery documentation (https://cloud.google.com/bigquery/docs/vector-index) needs a standalone, tested Python code sample demonstrating how to create an IVF vector index on embedding column (region tag bigquery_create_vector_index).

Solution:

• Add create_vector_index(project_id: str, dataset_id: str, table_id: str) -> None in bigquery/vector_search/bigquery_create_vector_index.py (Create an inverted file (IVF) vector index on an array embedding column in BigQuery using CREATE VECTOR INDEX.)
• Add unit tests (bigquery/vector_search/bigquery_create_vector_index_test.py) covering both the success path and API error handling (GoogleAPICallError)

Code Review

This pull request introduces a new Python sample script and unit tests for creating an IVF vector index on a BigQuery table. It also adds the necessary configuration and dependency files for testing. The feedback suggests updating the noxfile_config.py to remove Python 3.10 from the ignored versions list, ensuring that the oldest supported Python version is properly tested in accordance with repository guidelines.

[gemini-code-assist]

According to the repository's general rules, we should only test the oldest and newest supported Python releases in test configurations (such as noxfile_config.py), ignoring intermediate versions. Since requirements-test.txt specifies python_version >= "3.10", Python 3.10 is the oldest supported version and should be tested. Please remove "3.10" from ignored_versions.

Suggested change

	"ignored_versions": ["2.7", "3.7", "3.8", "3.9", "3.10", "3.11"],
	"ignored_versions": ["2.7", "3.7", "3.8", "3.9", "3.11"],
